Outdated
| Yes, it doesn't look like printf("Hello world"). Let's try to understand what is it and how it works. Take a look 1-2 lines. We defined data section and put there msg constant with Hello world value. Now we can use this constant in our code. Next is declaration text section and entry point of program. Program will start to execute from 7 line. Now starts the most interesting part. We already know what is it mov instruction, it gets 2 operands and put value of second to first. But what is it these rax, rdi and etc... As we can read in the wikipedia: | ||
| Looks quite long in a comparison to our usual well known `hello world` program. Let's try to figure our what is going on here and how it works. | ||

| Take a look first 4 lines of the program. We defined the data section and put there the `msg` constant with the `hello world!` value. Since the constant is defined in the `data` section, it could be used in the code of the program. The next is the declaration of the `text` section and the `_start` entry point of the program. After we will run the program, it will start to execute from the `_start` line. |
There was a problem hiding this comment.
Maybe we can introduce bullet points here? Something like:
Look at the first few lines of the program. Here, we define two sections:
datasection - This is where we place themsgconstant with the valuehello, world!. Since this constant is in thedatasection, we can use it in the program's code.textsection - This section contains the_startentry point of the program. When you run the program, it will start execution from the_startline.
